One millimole of `C_aSO_4` weighs _______ .
(Ca = 40, S = 32, O = 16)

A

136 g

B

13.6 g

C

0.136 g

D

0.0136 g

Text Solution

Verified by Experts

The correct Answer is:
C

One mole of `CaSO_4`
= gram molecular weight of `CaSO_4`
= 40 + 32 + 64 = 136 g
One millimole of `CaSO_4` `= 136xx10^(-3) = 0.136 g`
